Copovidone ni polymer yamazi akoreshwa mugutezimbere no gufata imiti yimiti itandukanye, harimo no kuboneza urubyaro.
Poly (1-vinylpyrrolidone-co-vinyl acetate) nigikoresho nyamukuru cyibikoresho byo kwisiga bikoreshwa mumisatsi gel, mousse, shampoo, nibindi, hamwe na surfactants, farumasi nibindi bikorwa byinganda. Zikoreshwa cyane nkibikoresho bifata amazi hamwe nudukoko twumye muri granulation hamwe na tekinoroji ya tablette itaziguye, nkibikoresho byo gukora firime mugutwikira firime, nkibintu byangiza imyanda mubikoresho byo guhisha. Ikoreshwa mugutwikira isukari kugirango wirinde gucika. Igikoresho cyo munsi yimiti ikoreshwa muburyo bwo kwirinda ubushuhe. Ibicuruzwa bya Vp / va copolymer bikoreshwa cyane cyane nkibikoresho byo gukora firime hamwe nuburyo bwo gutunganya ibintu mubijyanye no kwisiga, cyane cyane mubintu biturika, geles yimisatsi, mousse nibicuruzwa bya shampoo. Bafite uruhare runini nkibikorwa byo gukora firime hamwe nogukora imisatsi. Niba zikoreshwa hamwe na pvpk30, ingaruka zo gukoresha zizamurwa.
Ibigaragara ni ifu yera cyangwa ibara ritagira ibara. Ubwoko busanzwe ni PVP-64.
